Re: ceph same rbd on multiple client

    Hi,

    Waiting for CephFS, you can use clustered filesystem like OCFS2 or
    GFS2 on top of RBD mappings so that each host can access the same
    device and clustered filesystem.

    Regards,

    Frédéric.

      Hi All,

                We are using rbd and map the same rbd image to the rbd
        device on two different client but i can't see the data until i
        umount and mount -a partition. Kindly share the solution for
        this issue.

        Example

        create rbd image named foo

        map foo to /dev/rbd0 on server A,   mount /dev/rbd0 to /mnt

        map foo to /dev/rbd0 on server B,   mount /dev/rbd0 to /mnt

        Regards

        Prabu
